Æ25 - Gordian III ΘΥΑΤ Κ ϹΜΥΡ ΟΜΟΝΟΙΑ

The homonoia coinage struck between Thyatira and Smyrna reflects a formal alliance between two of the wealthiest cities in the Pergamene conventus, each competing aggressively for imperial favor and civic prestige during the third century. These homonoia issues were not sentimental — they were diplomatic instruments, often tied to shared festival rights, trade agreements, or joint embassies to Rome. Thyatira, a Macedonian colony with deep roots in textile and dyeing industries, had particular commercial reasons to court Smyrna's port access.

The reference VII.1#194 places this within Walther Weiser's corpus of Lydian bronzes — a relatively thinly documented series where die links between cities remain incompletely mapped.
